I want to take an aircraft engine cone texture from one aircraft and put it into another aircraft, I have already cut out the cone with mspaint but now how do I get it into another texture. My problem here is that it wont "fit" because of how tight the textures in one .bmp are packed. The only way to copy the thing from paint is to have a rectangular section, this obviously overlaps the existing texture.

You need a more sophisticated image editor such as Photoshop or Paintshop. MSPaint isn't really upto this.These will allow you to cut out whatever shape you want and paste it into the other image. The best way would be to post it into a separate layer (overlaying the base layer) enabling you to position and size it to fit.
